#### ImageDraw 提供了一系列绘图方法，绘制验证码

# 随机字段：
def rndChar():
	return chr(random.randint(65,90))

# 随机颜色
def rndColor():
	return (random.randint(64, 255), random.randint(64, 255), random.randint(64, 255))

# 随机颜色
def rndColor2():
	return (random.randint(32, 127), random.randint(32, 127), random.randint(32, 127))

# 240 * 60
width = 60 * 4
height = 60
image = Image.new('RGB',(width,height),(255,255,255))

# 创建Font对象
font = ImageFont.truetype('arial.ttf',36)
 
#创建Draw对象
draw = ImageDraw.Draw(image)

#填充每个像素
for x in range(width):
	for y in range(height):
		draw.point((x,y),fill=rndColor2())

#输出文字
for t in range(4):
	draw.text((60*t+10,10),rndChar(),font=font,fill=rndColor2())

#模糊
image = image.filter(ImageFilter.BLUR)
os.remove('code.jpg')
image.save('code.jpg','jpeg')
